Bug ID: 56731
           Summary: Allow specifying file system type for folder-based
                    drives [rekordbox]
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mountmgr.sys

Hi all,

currently, when the dosdevices link points to a folder instead of a device
file, wine will report NTFS filesystem type.

Rekordbox requires that we see a drive with GetDriveTypeW returning
DRIVE_REMOVABLE and GetVolumeInformationW reporting FAT32 filesystem. As
explained in https://bugs.winehq.org/show_bug.cgi?id=16091#c22, it is currently
not possible to override the drive type when specifying a device based drive
however.

https://bugs.winehq.org/show_bug.cgi?id=16091#c22 extends the device type
specification in the registry to enable a folder-based drive to report back as
DRIVE_REMOVABLE. But without further changes, it will always report back as
NTFS, which will make RekordBox complain about an unsupported filesystem type.

For testing, I patched mountmgr to always report FAT32 for DRIVE_REMOVEABLE
devices. But I'm not sure if this is a good solution. What do you all think?
